WHEEL FOR TRANSMITTING POWER.

SPECIFICATION forming part of Letters Patent No. 251,024, dated December20, 1881.

Application filed Mayi), 1881. (No model.)

To all whom it may concern Be it known that 1, ANDREW J. BRILL, ofCincinnati, Hamilton county, Ohio, have invented certain new and usefulImprovements in Wheels for Transmitting Power, of which the following isaspecification.

My invention relates to that class of wheels whose shafts have but onejournal-bearing; and the object of my improvements is to provide againstthe shaking or lateral motionthat is, a motion at an angle to the planeof revolution-which eventually results from the wear of the journal andshalt, my improvements being of such a nature as to prevent theoccurrence of said shaking or lateral motion.

Figure l is a perspective view of my invention, showing it in positionfor operation. Fig. 2 is a sectional elevation. Fig. 3 is a frontelevation. Fig.4 is a sectional elevation of the modified modeofattachment to the leg. Fig. 5 is a sectional elevation of amodification of the invention.

Similar parts are designated by similar letters.

A is the wheel, or my invention proper, preferably a grooved pulley, asshown in Fig. 1, attached to the side leg, B, of a sewing-machine orlathe, power being preferably transmitted by the pitman O and treadle D,constructed in the usual manner, the belt E carrying the motion or powerto the working mechanism.

The wheel A consists simply of a ring orrim, made of any desired size,its periphery being either smooth, grooved, or provided with teeth orother devices for transmitting the powerimparted to the wheel. The inneredge of this ring or rim has a groove, a, of a suffieientdepth to permitthe rim A to fit closely and snugly around the outer ends of thestationary spokes F F, which are rigidly secured to the side leg, B, ina manner hereinafter described. This inner groove, to, may be formed inthe rim, or be formed by bolting flanges to the sides of the rim, and inthe latter event both the exterior and interior grooves may be formed bymeans of suchfianges. The outer ends of these spokes F are eitherslightly rounded, or, as shown in the drawings, they may be providedwith the friction-rollers f f, or the spokes may be dispensed with, anda solid piece, or other equivalentdevice, be used instead. either withor withoutthe friction-rollersf. The use of such rollers is preferable.

The groove to may be placed in the fixed portion represented by thespokes when no rollersfare employed, the rim A being provided with anannular tongue, at, or rollers fitting into said groove, and whenrollerfis located in the end of the spokes, as hereinbefore mentioned,the tongue to will fit therein. The rim A will thus in either case bekept in place while rotated. The spokes, or their equivalent device, arerigidly fastened to leg B by the bolt G, passing through the center orintersection of the spokes into the lug H upon the leg B. There notbeing, as arule, any lug or equivalent on the leg of an old machine, itbecomes necessary, in order to give a suffieient depth of hearing to thebolt G, to introduce the washer H between the side of the wheel and theleg, as shown in Fig. 4.

Suitable means of taking up the wear, either in the inner groove, a, ofthe rim A or the ends of the spokes F, or friction-rollers f, arepreferably provided. A desirable mode of taking up said wear is asfollows: The spokes F are formed at their inner ends with slots f,corresponding in width to the diameter of the bolt G, and of asufiicient length to allow for any amount of wear, the spokes being madeof sufficient length to allow for any extension outward, and at the sametime to leave sufficient material on each side of the bolt G. Each spokeis preferably cut away at the point where the slot f begins sufficientlyto allow the slotted end of its diametrically-opposite spoke to lieeither under or above its own slotted end, and the slotted ends of eachpair of spokes diametrically opposite are also still further cut away,so that the slotted ends of thepair crossing them lie either under orabove their own slotted ends, as will be more fully understood byreference to Figs. 2 and 3.

When itis desired to adj ust-anyof the spokes the bolt G is loosened,the spoke moved in or out as far as desired, and the bolt againtightened.

As a means of connecting the pitman O to the rim A, and therebyimparting motion, a yoke, J, in the present instance archedto avoidcontact with the head of the bolt G, is provided, passing from one sideof the rim A to a point diametrically opposite on the other side, andsecurely fastened to said rim, the yoke being raised sufficiently toenable it to clear the head of the bolt G, and the pitman (J beingconnected to the yoke J at any suitable point and in any approvedmanner. The yoke J also serves to strengthen the rim A, and for thispurpose more than one may be used, if necessary. The spokes, or theirequivalent, being fastened rigidly to the side or legB. and power beingtransmitted to the rim A, it revolves freely around the periphery of thestationary device,being kept in place by theinner groove, a, the bolt Gfirmly holding the spokes, or their equivalent, and preventing anylateral or shifting motion.

What I claim as new and of my invention, and desire to secure by LettersPatent, is

1. The pulley-rim A, so constructed as to be retained upon and revolvearound a fixed frame, substantially as herein described.

2. The combination of the rim A and spokes F, or equivalent device,constructed and operated as described.

3. The spokes F, rim A, and friction-rollers f, constructed andoperating as herein set forth.

4. The slotted spokes F, rim A, and bolt G, as herein described, and forthepurposes specified.

5. The rim A, in combination with the yoke J, or equivalent, constructedand operated as herein described.

6. The pulley-rim A, provided with groove 00, so constructed as to beretained upon and revolve around a fixed frame, substantially as hereindescribed.

7. The combination of the rim A, provided with groove 00, and spokes F,or equivalent device, constructed and operated as described.

8. The spokes F, rim A, provided with groove d, and friction-rollers f,constructed and operating as herein set forth.

9. The slotted spokes I rim A, provided with groove a, and bolt G, asherein described, and for the purposes specified.

10. The rim A, provided with groove a, in combination with the yoke J,or equivalent, constructed and operated as herein described.

11. The pulley-rim A, so constructed as to be retained upon and revolvearound a fixed frame capable of adjustment toward and from the said rim,substantially as and for the purposes specified.
